CUSHION-FORMING MACHINE.

To all whom it may concern:

Be it known that I, J AOOB H..LnviN, a citi- Zen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented, certain new and usefullmprovements in Cushion- Forming Machines, of which the following is a specification. v

My invention relates to cushion forming machines and has for its object to provide amachine which will facilitate the manufacture of cushions. A further object is to provide a machine which will hold the padding properly in place while'the cover is applied.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claim. 1

Referring to the drawings which illustrate my invention in apreferred form of construction,

Figure 1 is a top plan view. Fig. 2 is a. view in side elevation. Fig. 3, is a view mostly in longitudinal vertical section. Fig. 4 is a view in section on line 4-4 of Fig. 1 Fig. 5 is aview in section 011 line 5-5 of Fig. 4. Fig. 6 is a view in front elevation. Fig. 7 is a detail in section showing the application of the cover. Fig. 8 is a view in section showing the machine in operation. Fig. 9 is a view of the cushion showing the cover as it is applied during the operation of the machine. Fig. 10 isa view of the cushion completed. Fig. 11 is a detail in side elevation of the front of the machine as viewed from the left in Fig. 1. Fig. 12 is a detail in bottom plan of the plunger. Fig. 13 is a side view of the plunger.

Referring to the drawings, a table top 1.4 is supported on front legs 16 and 18 and rear legs 20 and 22. The front and rear legs are connected near the bottom by longitudinal bars 24 and at the top by longitudinal bars 26. The longitudinal bars 26 are eX- tended at the rear as is also the table top, to which is secured the curved casting 32 across the curved portions of which are a series of slats 3st constituting a support for a roll of cotton or other padding material 36. The rear legs are connected by transverse bars 38 and 40 to which, by means of the angle irons 42, is secured a housing 44: which will be referred to later.

Specification of Letters Patent.

Application filed May 31, 1918. Serial .No. 237,548.

The forward bottom side of the table top 11 is provided-with a slide-way formed by sidemembers 4c spaced from each other and secured near the central portion of the table, as shown in Fig. 4. Mounted for slid.- ing movement in this slideway is a member 48 in the upper-side of which is set'an iron plate 50 secured-by screws, as shown in Figs. 3 ands and through which extends one or more pairs of. cooperating holes 52. There may be three of these pairs of holes for the purpose of adjustment, as shown in Fig. 1 and in longitudinal line with each pair of these holes there are slots in the table top. These slots and holes are provided to permit movement of a plunger having a head 56 to which secured a stem 58 strengthened by braces'60. On the rear of the stem is secured a. plate 62' having two projections 64 to eX- tend through one of the slots 54 into one pair ofholes 52in the slide. To the rear end of the slide is secureda cord 66 extending over a roller 68 which depends from the table and to the other end of this, cord is secured a counter;.-eiglit 70 adapted to move up and down in the housing as previously referred to. Tothe front end of the slide is. secured another cord 72 extending over a roller 74 which depends from the table and the other end of this cord is secured to and adapted to wrap around a pulley 7 6 secured to a shaft 78 which is mounted for rotation in bearings 80 on the front legs. To the shaft 78 is secured a smaller pulley 82 around which is wrapped a strap or flexible member 84, the other end of which is secured to a lever 86 pivoted at 88 to a hanger 90 near the rear portion of the machine. On the front end of the lever is secured a foot pedal 93. At the front of the machine is a holding board 92 spaced above the table and adjustably secured in position by thumb screws 94: passing through slots in the supporting members 96. On the upper side of the table is a fixed guide 98 and an adjustable guide 100, the latter being best shown in Figs. 1, 4 and 11. Mounted for sliding movement in a dove-tailed slot 102 is a slide 104 secured to the guide 100 by a bolt and by braces 106. A thumb screw 108 serves to secure the slide in adjusted position. It is evident that this slide according to the position in which it is adjusted may be used in connection with any one of the three sets of slots in the table and the three sets: of holes in the slide previously referred to. her 110 preferably of metal and open at the front and rear is adapted to be slid between the guides 98 and 100 and under the holding 7 board 92. A stop 112 at the rear of this member limits the amount of the forward movement. The rear of the member 110 is preferably beveled, asshown atll l, to facilitate the introduction of a cushion. 1 The top of this member is formed by two hinged covers 116.

The operation and advantages of my ma chine will now be obvious. It is adapted particularly for use in covering cushions, the interior portions of which are formed of helical springs, as shown in Fig. 4, held together in any suitable manner, and which may be purchased in this form. In use the inclosing member 110 is placed on thetable in the position shown in Figs. 41 and 5 with the hinged covers 116 open. A suitable amount of cotton is taken from the roll 36 and spread on the bottom of said member. The cushion foundation is then placed on the top of this cotton and more cotton is spread over and around the cushion founda tion. The hinged covers are then closed and the member 110 containing the inclosed cushion is forced by hand under the holding board 92 with the front end of said member protruding, as shown in Fig. 7. A fabric cover stitched together except near one end is then forced Or drawn by hand over the protruding end of the cushion leaving the unstitched end turned back and depending, as shown in Fig. 7. With the plunger 56 in proper position with the projections 64: ex-

An inclosing memtending into the holes in the slide 48 the operator steps on the foot pedal 93 and forces the cushion out of the inclosing member 110. Fig. 8 shows this operation partly completed. When the cushion has been entirely ejected from the member 110 it will be found that. the padding is held in place by the stitched cover and that the unstitched end thereof may be quickly drawn around the cushion and stitched in place to form the completed cushion, as shown in Fig. 10. When the operator releases the foot pedal the counter-weight will quickly draw the slide and the connected plunger back into 7 position for operating upon another cushion. Cushions may be formed much more expeditiously by the use of my machine and the cotton padding is held in proper place while the cover is being applied to the machine.

- I claim: 7

A cushion forming machine comprising slide movable in said guide-way for moving saidplunger, a footpedal and operating connections between said pedal and said slide.

' In testimony whereof I hereunto aflix my signature.
